The BBC was found to have committed a "serious breach" of broadcasting rules by omitting to mention that the voice of a film about the Gaza conflict was the child of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, stating there had been "a serious error in relation to accuracy".
Ofcom has directed the corporation to transmit a peak-time announcement about its decisions.
"As this represents a major infringement of our code, we are ordering the broadcaster to air a message of our determinations against it on BBC2 at 21:00, with a schedule to be determined," it said.
'Risk to Erode Trust'
The watchdog's statement declared: "The inquiry we conducted concluded that the film's omission to reveal that the presenter's father served in a role in the Hamas-controlled government was significantly deceptive.
"This implied that the audience did not have vital facts which may have been extremely pertinent to their assessment of the voice and the content he provided.
"Confidence is at the center of the relationship between a television network and its viewers, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the potential to erode the very considerable levels of credibility that the public would have placed in a documentary produced by the BBC about the Gaza conflict."
The programme was pulled from iPlayer in last February after the narrator's familial connections were revealed, and in the month of July an internal BBC review concluded it violated the organization's journalistic standards on truthfulness.
A BBC spokesperson stated: "The authority's determination is in line with the results of the corporation's inquiry, that there was a serious error in the documentary in relation to the BBC's Editorial Guidelines on accuracy, which aligns with regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we comply with Ofcom's decision in full. We will comply with the directive as soon as the timing and wording are finalised."
